PERSONALIZED PROSTHESIS AND METHODS OF USE
A personalized prosthesis for implantation at a treatment site of a patient includes a self-expanding mesh or membrane having collapsed and expanded configurations. The collapsed configuration is adapted to be delivered to the treatment site, and the expanded configuration engages the personalized prosthesis with the treatment site. The mesh or membrane is personalized to match the treatment site in the expanded configuration, and has an outer surface that substantially matches the treatment site shape and size. The self-expanding mesh or membrane forms a central lumen configured to allow blood or other body fluids to flow therethrough. Methods of manufacturing and delivery of the personalized prosthesis are also disclosed.
STENT PUSHER ASSEMBLY
Provided is a stent pusher assembly for positioning a ureteral stent, the stent pusher assembly having an inner and outer stent pusher. The stent pusher assembly positions the ureteral stent in a patient's kidney and bladder without a bladder fixing portion of the stent entering a ureteral passage-way, thereby minimizing irritation to the patient.
Stent
In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.
DEVICES AND METHODS FOR CLOSURE OF TRANSVASCULAR OR TRANSCAMERAL ACCESS PORTS
The present disclosure provides a variety of prostheses, delivery systems and techniques to facilitate closure of transvascular or transcameral access ports. Various embodiments of prostheses are provided including a plurality of radially expandable discs that can be filled with material to facilitate coagulation and to reduce or stop leakage from punctures in vessel walls.
ANTIBIOTIC DISPENSING SPACER APPARATUS AND METHOD FOR INFECTED TOTAL KNEE ARTHROPLASTY
A spacer for a knee replacement prosthesis. The spacer may have a lower surface with a locking component adapted to interlock with a tibial tray, an upper surface optionally with a tibial post and a pair of smooth-surfaced and slightly concave condyle support platforms disposed on opposite sides of the tibial post, and a substantially hollow body with an internal reservoir that can be filled with antibiotic material. The reservoir may be accessible from a port on the hollow body that leads into the internal reservoir, and which permits refilling of the reservoir. In some embodiments, the reservoir may be refillable from this port without removal of the spacer from the patient; for example, a percutaneous needle may be inserted into the port. The spacer may dispense antibiotic from this reservoir to the surrounding area in order to treat an infection.
Flexible endoluminal device
The present disclosure describes endoluminal devices, such as stents and stent grafts capable of being bent smoothly, with various benefits resulting therefrom.
Intervertebral prosthesis
An intervertebral prosthesis for insertion between adjacent vertebrae includes upper and lower prosthesis plates locatable against respective vertebrae and having opposing concavely curved recesses therein, and a core located between the plates. The core has opposed, convexly curved surfaces received in the recesses of the plates to allow the plates to slide in articulated manner over the core. The opposed surfaces of the core and the recesses of the plates have cooperating spherical curvatures. The recess of each plate surrounds a locating peg projecting centrally from the base of the recess and is bounded by an annular rim, such that the annular rims of the plates are arranged to contact one another at a predetermined limit of sliding movement of the plates over the core. The peg locates loosely in an opening located centrally in a curved surface of the core, whereby the plates can slide over the core in all directions while the peg holds the core captive.
Stents and related methods
Stents are disclosed herein. In some embodiments stents within the scope of this disclosure may comprise a first flared end and second flared end. In some embodiments, a profile of each of the first flared end and the second flared end may circumscribe a portion of separate elliptical arcs. In some embodiments, the stents are formed from braided or woven wires having a constant pitch along a middle region and continuously varying pitches along the first flared end and the second flared end. Methods of manufacturing stents are disclosed herein. Methods of using stents are also disclosed herein.
METHOD AND APPARATUS FOR PERFORMING SPINE SURGERY
Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.
IMPLANTABLE MEDICAL DEVICE WITH CAVITATION FEATURES
In some examples, the disclosure describes a medical assembly that includes a stent including a primary electrode, where the stent is configured to expand from a collapsed configuration to an expanded configuration, a secondary electrode, and an energy source configured to deliver an electrical signal between the primary electrode and the secondary electrode through a fluid in contact with the primary electrode to cause the fluid to undergo cavitation to generate a pressure pulse wave within the fluid.
